New version of assertive and answers to tutorial exercises

I gave a tutorial at useR on testing R code, which turned out to be a great way of getting feedback on my code! Based on the suggestions by attendees, I’ve made a big update to the package, which is now on CRAN. Full details of the new features can be access in the ?changes help page within the package.

Also, the slides, exercises and answers from the tutorial are now available online.
